MACHINE FOR SC'RA PING AND SPLITTING CANE.

SPECEFICATIQII forming part of Letters Patent No. 307,276, dated October28,188

Application filed April 20, 1883.

To all whom it may) concern.-

Be it known that I, EDWARD M. ELLIS, of Gardner, in the countyofllforcester and State of Massachusetts, have invented a new and ImprovedMachine for Scraping and Splitting Cane, of which the following is afull, clear, and exact description.

The object of my invention is to provide a new and improved machine forscraping cane so that it will have a uniform smooth surface throughout,and then splitting the cane longitudinally into a number of pieces ofprecisely the same size.

A further object of my invention is to provide new and improved devicesfor automatically separating the blades of the scraping mechanism of themachine in such a manner that the cane can be passed in between the inner ends of the said blades, and then closing the blades on the canethat has been inserted.

The invention consists in a machine constructed with a series of feedrollers, with a mechanism for scraping the cane or rattan, and with asplitting -knife for splitting the cane into a number of parts, in frontof which scraping devices and splitting knife Suitable centering devicesare provided, which conduct and guide the cane in such a manner that itpasses precisely centrally through the scraping and splitting devices.-

The invention further consists in the combination, with the feed-rollersand the scraping devices, of a series of levers, latches, and othermechanism so combined and arranged as to automatically separate thecutting ends of the blades to admit the cane between them, and then toautomatically press the cutting ends of the said blade on the cane.

The invention further consists in feed-rollers which can be adjustedaccording to the thickness of the cane or rattan, which feedrollers areadjustably mounted on the upper ends of vertical shafts.

The invention also consists in various parts and details and numerouscombinations of the same, as will be fully described and claimedhereinafter.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Fig. 16 is aside view of the saidmechanism,partsbeingshowninsection. Fig. 17 isa side view of the cam andthe disk on which it is mount-ed. Fig. 181s a longitudinal sectionalelevation of part of the clamp ing half-rings and the disk on which theyare held.

In a horizontal platform, A, supported by a frame, A, a series ofvertical shafts, B, are journaled, the two longitudinal parallel rows ofshafts being divided into three sections, each containing an equalnumber of shaftsin the case shown six. Below the platform A a cog-wheel,B, is mounted on each shaft B, the several cog-wheels B engaging witheach other, and cog-wheels B are interposed between those cog-wheels, B,which are separated too far to engage with each other. The driving-shaftC of the machine, provided with fixed and loose driving-pulleys, isjournaled in the frame A, and is provided with a beveled cog-wheel,which engages with another beveled cog-wheel mounted on the same shaft lwith one of the wheels 13*, so that if the said Fig. 8 is alongitudinalsectional elevation cog-wheel B is rotated the entire train of the l inan annular ridge or collar, F, formed around cog-wheels B and B will berotated and will rotate the shafts B. The cog-wheels are to be soarranged that the shafts B of each row will revolve in the samedirection, andthe shafts of the opposite row will all revolve in thereverse direction. so that if a piece of cane or rattan is passed inbetween the feed-rollers D, mounted on the upper ends of the shafts B,the said iced-rollers will draw the cane or rattan through the spacebetween the rollers.

' rests, which is held fixed on the shaft B by a key, A provided with aspline or feather, a, passing into a vertical groove, a, in the verticalaperture of the roller, which key fits into a recess in the upper end ofthe shaft B. A cap, D, held by a screw on the upper end of the shaft,holds the pulley or roller D in place. The pulley or roller D isprovided with a central circumferential groove, (1, above which asmaller circumferential groove, d, is

provided, and below the grooved a still smaller circumlerenlial groove,(Z is provided. The pulleys or feed-rollers D are above the platform A,and when the feed-rollers D rest on the collars b the grooves (1 will besuch a distance above the platform A that a piece of cane or rattan heldin the grooves d of two adjoining rollers will be such a height abovethe platform A that it will be in the proper position for being fedcentrally to the scraping and splitting knives or cutters. If a largercane is to be scraped and split, the pulleys D are inverted, so that thegrooves d will be at the desired height above the platform A. If a stilllarger or thicker cane or rattan is to be passed through the machine,the same must be held in the grooves d, and to bring them to the properheight abovethe platform A the collars b are removed, so that thefeed-rollers D will rest directly on the shoulders I). It is naturalthatall the feed-rollers D on the platform A must be adjusted in the samemanner. Between the first set of six feed-rollers and the second set ofsix feed-rollers a disk, E, is held transversely and vertically on theplatform A in such a manner that the center of the said disk willcoincide with the intersection ofthe vertical plane between thefeedrollers and the horizontal plane of the centers of the lowestguide-grooves in the feed-rollers-that is, the center of the disk E isto be on a line with the center of the rattan or cane held between thefeed rollers.

On the disk E a series of radially-sliding scraping-blade holders, E,are 1nountedin the case shown nine-which are divided into groups ofthree each. The outer ends, E of the scraper-blade holders E are madecylindrical, and passed through sleeves 0, held in the outer ends of thearms on the disk E. The inner ends of the scraper-blade holders E passthrough wedge-shaped recesses F, formed the central aperture of thediskE, the scraperblade holders thus being adapted to slide radially in thesleeves e and in the dovetailed grooves F. The bottoms or under ends ofthe dovetailed grooves F are not all the same distance from the surfaceof the disk E, for, as stated above, the scraper-blz-ide holders aredivided into three groups of three each. The bottoms of the dovetailedgrooves or recesses 13 of the first group, marked l, in Figs. 8 and 4:,are a greater distance from the surface of the disk'E than the bottomsof the recesses of any of the other scraper-blade holders. The bottomsof the grooves or recesses F of the second group of scraper-bladeholders, marked 2, are nearer the surface of the disk E, and the bottomsof the grooves E of the third set of scraper-blade holders, marked 3,are nearest to the surface of the disk E, so that the ends of thescraper-blade holders will be arranged in three short spiral lines,extending from the front to the rear; or, in other words, thescraper-blades attack thesurface of the cane in three different verticalplanes, one behind the other. Curved scraper-blades G are held in thescraper-blade holders E and the cutting-edges project from the ends ofthe blade-holders, which blades are held in place by means ofbinding-screws G. A spiral spring, G, surrounding the rounded part ofeach scraper-blade holder, presses the said holder toward the center ofthe disk, and presses a stud or pintle, 0, projecting toward'the surfaceof the disk E, upon the edge of the cam-tooth H of a cam-wheel, H,surrounding the annular ridge E and resting on the surface of the diskE, which camwheel is provided with one cam-tooth for each scraper-bladeholder. The caurwheel H is provided with a downwardly-projecting arm,

H to the lower end of which an arm, H is.

pivoted, which is mounted rigidly on the end of a rocking shaft, 1.Directly in front of the disk E a plate, J, rests upon the platform A,which plate J is provided in its bottom with a longitudinal ridge, 7',which passes into a corresponding groove in the platform A, thus guidingthe plate J when the same is moved longitudinally. The plate J is heldon the platform A by a screw, J, passing through a longitudinal slot, Jin the plate J, thus permitting of a longitudinal adjustment of the saidplate.

On that end of the plate J toward the disk E two standards, K K, areprovided, on the upper end of each of which a horizontal disk or wheel,K, isjournaled, the edges of which disks are in contact. The disksareeach provided with a semicircular or almost semicircular recess, K3,in which recesses, when they are opposite each other, a beveled plug, L,is held, which causes the guide-rollers to swing together, so that oneguide roller cannot swing in advance of the other,and is provided with ahead, L, to prevent it from dropping.

On the upper surface of each disk K a 7 ends of the plate J.

standard, L is provided at that side of the 1 swing in the verticalplane, and pivoted to recess K? toward the disk E, and on each standardL a guide pulley, L, is loosely mounted, which guide-pulleys areprovided with two circumferential grooves, land Z, of which the formeris larger than the latter.

From the rear-parts of the edges of the disks K studs k project, towhich a spiral spring, is attached,which pushes them from each other; orthe spring can be attached to the opposite sides, and then can bearranged as a tension-spring. By the action of the spring the rollers Lare pressed toward each other so that their edges will be in contact.

The splittingknife M consists ofatuhe having its end sharpened, whichtube is provided with as many radial longitudinal ribs in as the cane orrattan is to be split into pieces or parts, which ribs have their outerends sharpened, the inner ends of the grooves formed between the ribsbeing tapered toward the rear end of the tubular knife. The tubularknife M is secured inthe front end of the tubular projection M,projecting outward from the lower part of a scoop-shaped u pwardly-curved guide,

M, the tubular projection M extending en tirely through to the rear sideof the scoop or guide N, and forming a guide-tube, N,through which thecenter or pith of the split rattan is conducted. Directly in front ofthe end of the splitting'knife M a guide is located,which is constructedlike the guide in front of the scraper-blade disk E; but in this casethe standards K are secured on a plate, 0, held by a dovetailed ridge inits bottom, to slide transversely on the adjustable plate J. The plate 0can be adjusted and locked in the desired position by means of thescrews 0, passing into the end of the plate 0, and held to turn 011upwardly-proiect-ing flangesO" on the The standards K can be adjustedvertically, so that the central axis of the opening between the grooves,through which opening the scraped rattan passes, will coincide preciselywith the longitudinal central axis of the cane-splitting knife M.

t its front end the platform A is provided with a funnel -shaped orconical horizontal mouth-piece, 1?, into which the cane passes, whichmouthpiece conduct-s it in between the feed-rollers D. Between the firstand second pair of feed-rollers a standard, 1?,is held on a plate, Pdovetailed in the platform A, in the upper end of which standard I? atube, P is held horizontally and parallel with the plane between the tworows of feed-rollers D, which tube P is located at such a height abovethe platform A that the cane passed between the first two feed-rollers Dwill he conducted into the said tube. In one side the tube P is providedwith a longitudinal slot, 1), into which a pulley, Q, projccts,wliich isjournaled in the forked end of a rod, Q, in such a manner that the saidpulley Q can revolve in the horizontal plane. The other end of the rod Qis pivoted to the upper end of a lever, Q adapted to an arm of themachine-frame A, the lower end of which lever Q is pivoted to acrankarm, It, on the end of a shaft, It, journaled on the machine-frameA, which shaft R is provided at its opposite end with a downwardlyprojecting arm, R in the lower end of which arm a latch-lever, R ispivoted, which has one end made horizontal and the other end curvedupwardly, the upwardlyciently to permit the end of a bar, T, to rest onthe same, which bar T is pivoted between the outer ends of arms S of twoclamping halfrings S, )ivoted to each other diametricallyopposite to theinner ends of their arms S", which clamping halfrings surround a disk,T, rigidly mounted on the driving-shaft G of the machine. A rod, Tfastened on the lower arm S passes loosely through an aperture in theupper arm 8*, and is surrounded by a spiral spring, I, the upper end ofwhich is held on the rod T and the lower end of which spring presses onthe upper arm S, and thus presses the two arms 5* together. The hinge ofthe half-ri ngs S is connected by means of a pintle,

f, with a disk, a, mounted loosely on the driving-shaft O, with whichdisk to a cam, V, is made integral or to which disk the cam is attached,so that the cam and disk are mounted loosely on the shaft 0. The pintlef passes through a curved segmental slot, a, in the disk at, and isfastened in the desired position in the said slot by means of a nut, f.The position of the cam in relation to the halfrings S can thus beadjusted by means of the pintlef and the nutf.

On the edge of the cam V a rod, W, rests, the upper end of which ispivoted to an arm, WV, of the horizontal shaft I, which is pro vided atits opposite end with the arm H pivoted to the lower end of the arm H ofthe camwheel H on the disk E. The arms H and V form an obtuse angle.

Between the feed-rollers D standards Y are held, which are provided.with apertures parallel with the longitudinal axis of the platform A,through which apertures the pieces of rattan pass, and are thus guided.

Since it is necessary that a number of feedrollers be employed to obtainsufficient friction to maintain the required velocity of the stick and.guide the same to the knives, and since it is likewise necessary thatthe guide tubes be arranged a sufficient distance from thescraping-knives to allow their automatic The outer end of the slidingbar S projects from the frame of the machine suffioperating mechanismsufficient time to open and close them while the stick is passing thedistance occupied by the said rollers, in order to do this, and at thesame time insure the feeding of the cane in a straight line to theknives, I arrange some of the feed-rollers between the guide-tube andknives.

The operation is as follows: The cane or rat tan to be split has itsends cut off square, is passed through the mouth-piece 1?, passes inbetween the groove (1, d, or d of the first pair of feed-rollers and isdrawn inwardthat is, in the direction of the arrow aby the same, and ispassed into the tube P, and, pressing against the edge of the pulleyQ,presses the same sidewise-that is, in the direction of the arrow 1) ofFig. 14-1nore or less, according to the thickness of the cane or rattan,and,after passing through the tube P, the cane is seized by the otherfeed-rollers D, and is drawn in the direction of the arrow a until itsend strikes against the guide-rollers L in front of the disk E andpasses in between the same, separating the rollers more or less,according to the thickness of the rattan. Both rollers will be pushedapart or separated equally, and the center of the rattan or cane willalways coincide with the central line between the two rollers. If theend of the rattan or cane does not pass directly into the space betweenthe rollers, but strikes the surface of one of the rollers, it will beguided by the said roller to the space between the two rollers, and thenwill be guided straight to the center of the cutting disk E, thecutter-blades of which plane off or scrape and shave the joints of therattan. From the disk E the rattan or cane is carried by the otherfeedrollers D to the Centeringrollers L in front of the splittingknifeM, and is guided by the said centering device in such a manner that thecenter of the rod will coincide exactly with the center of the knife M.The feed-rollers press the end of the cane or rattan against the cuttingend of the knife M, whereby the cane will be split into as many equalparts as there are radial wings on the knife M, and the pith orremaining cen terofthe rattan passes through the tube N, and is seizedby the rear rollers D and carried off. The strips into which the rattanhas been split slide up the inclined scoop N and are carried off. As theknife M projects from the curved surface of the scoop N, those stripswhich pass over the upper part of the knife M, as well as those whichpass under the lower part of the knife M, will be guided upward by thesaid scoop. The ends of the scraper knives or blades are to be separatedautomatically to admit the cane between them. This is accomplished inthe following manner, as stated above. The cane, passing through thetube 1?, presses the rod Q in the direction of the arrow 12', there byturning the lower end of the lever Q", the arm It, and the shaft R inthe direction of the arrow 0. By this movement the arm It of the shaft Ris also moved in the direction of the arrow 0, and the end of thelatch-lever R bar S from under the end of the bar '1, held between theclamping half-rings S"; butif the latch-lever R" moves in the directionof the arrow 0 its curved end strikes against the bar r, and therebythatend of the latch-lever R resting against the head S of the slidingbar S will be released, and the bar S will immedi ately be drawn back inthe inverse direction of the arrow 0 by the spring 8. As long as the barT rests on the sliding bar S the clamping half-rings S cannot be lockedon the disk T, for the moment they become locked they exert a downwardpressure on the pivoted end of the bar T, and as the opposite end of thebar T rests on the sliding bar S the pivoted end of the bar T willseparate the arms S of the clamping half-rings S sufficiently to releasethe clamping half-rings from the disk T and prevent the revolving of thehalf-rings; but as soon as the sliding bar S is withdrawn for a momentby the latch-lever R the outer end of the bar T will be released, andthe spring I, surrounding the standard T presses the two arms Stogether, and thus clamps the half-rings S on the disks T, therebycausing the said half-rings S to be revolved with the disk T. As thepintlef connects the joint or hinge of the half-rings Siwith the loosedisk at, the said disk will be revolved, as will also the cam V, secured011 the said disk, whereby the rod V will be moved upward and will moveupward the outer end of the arm Y" of the shaft I, whereby the arm H atthe other end of the shaft I will be moved in the direction of the arrowa but the free end of the said arm H is connected with the lower end ofthe arm H of the cam-wheel H, provided with the several cams H. The saidcams will all be moved in the direction of the arrow (f -that is, theymay be forced against the pint-1e c of their respective blade-holdersEand will move the several bladeholders toward the periphery of the diskE such a dis tance that the end of the cane can be passed in between theinner ends of the cutter-blades. The blades G are moved outward untilthe end of the rod W slips over the cam V, when the springs G force theblades inward and against the surface of the cane that has been passedin between the separated inner ends of the blades. The blades will thenall rest on the surface of the cane, and as the .cane is moved in thedirection ofthe length of the machine they will scrape the surface ofthe same. The cane acts on the leverQ as soon as it is introduced intothe tube P; but some time is required for the transmission of themotion, and the scraper-blades of the scraper will be separated therequired distance to admit the end of the cane just at the time that theend of the cane arrives at the scraper. The length of the movement ofthe rod Q must always be the same for a thick or for a thin cane. If thecane is very thick, the wheel Q, held in the IOO end of the arm Q, mustbe made smaller than if the cane is thinthat is to say, the diameter ofthe wheel Q must increase as the diameter of the cane increases, and themachine must be adjusted for each size of cane. The knives and thecutting mechanism must also be adjusted for each size of cane, asmustalso the splitting device.

This machine does not automatically adjust the knives according to thethickness of the cane; but it separates the knives automatically andcloses them on the surface of the cane automatically.

I am aware that in a rattan scraping and splitting machine feed-rollershave been arranged in front of the radially-moving scrapjug-knives, witha stationary guide between said feed-rollers and a springpressed guidebetween the rollers and scraping-knives, and I therefore do not claimsuch invention.
